Title: Shortcircuit prevention of metallic wiring
Inventor: MORI HISATOSHI
IPC: H01L21/768
Filed: 1989-02-07
Abstract: PURPOSE:To prevent the shortcircuit between metallic wirings from occurring by a method wherein, after forming an insulating layer covering a lower layer metallic wiring, the lower layer metallic wiring is etched through the intermediary of a pinhole or a crack caused during the formation of this insulating layer so as to remove the contact part between the said pinhole or the crack and the lower layer metallic wiring. CONSTITUTION:A metallic film is deposited on the surface of an insulating substrate 1 and then the film is patterned to form a gate electrode 2. Successively, a gate insulating layer 3 such as SiN, SiO2 etc., is deposited on the whole surface including the gate electrode 2. At this time, a pinhole 7 or a crack 8 caused in the gate insulating layer 3 reaches the surface of the gate electrode 2. Later, when the gate insulating layer 3 is dry-etched downward using plasma, the gate electrode 2 is etched away to pick caves 2a. Next, an alpha-Si semiconductor layer 4 is deposited to be patterned on the gate insulating layer 3. Then, another metallic film is deposited to be patterned on the whole surface so as to form a source and a drain electrodes 5, 6. Through these procedures, the shortcircuit between the metallic wirings can be prevented from occurring without fail.

Title: Ultrasonic transducer
Inventor: SUZUKI KENICHIRO
IPC: G01S7/52
Filed: 1987-02-12
Abstract: PURPOSE:To achieve a uniform characteristic and a higher performance, by arranging the surface of a second electrode on a semiconductor substrate to be higher than the circumferential surface thereof. CONSTITUTION:One main surface of a silicon substrate 1 is so worked so that the surface of a lower electrode 6 is higher than the surface of the circumference 29 thereof. Thus, the electrode 6 comes in close contact with a polyester film 48 to allow a reduction in a fine gap between the surface of the electrode 6 and the film 48. This lessens the electrostatic capacitance between the upper and lower electrodes 49 and 6 due to this fine gap thereby enhancing the sensitivity in transmitting/receiving characteristic of a device.
